Ebay did the same to me on two auctions I won. I bought some Spektrum 6100E receivers from two different sellers who had great feedback. I only paid about $4 a piece from one seller so I got 6 and $6 from another so I bought two from him. A few days later, both listings were gone like they never existed. They came in so I wasn't defrauded outright, but I am wondering now if they are counterfeit. They look authentic and I will test them today to make sure they work, but I am kinda screwed if they don't...
